2) Create a table called CGPA(ID, cgpa) which stores current c.g.p.a for each student and points : 20 write a trigger on the GradeHistory table which automatically updates the CGPA table while any changes happen.

For the following relation schema: Students(ID, name, status) Grade History(ID courselD, courseCredit, grade_point) Friend(ID1,ID2) Likes/ID1, D2) Friend table represents unidirectional relationships .e if id1 = 1510 and id2 = 1381 means 1510 friends with 1381 but not vice versa. Likes table represents unidirectional relationships ie if id = 1689 and id2 = 1709 means 1689 Likes 1709 but not vice versa. The four years of undergraduate education are called: freshman, sophomore, junior, Senior.
